Parenting and addictions: Current insights from human neuroscience

Area of Science:

• Neuroscience
• Addiction Research
• Developmental Psychology

Background:

• Maternal substance use and addiction are linked to alterations in the maternal brain.
• Understanding neurobiological mechanisms is crucial for addressing caregiving challenges in mothers with addiction.

Purpose of the Study:

• To explore neurobiological mechanisms underlying caregiving behavior in mothers with substance use disorders.
• To inform the development of novel parenting interventions informed by neuroscience.

Main Methods:

• Review of human neuroimaging studies examining maternal brain function and structure.
• Analysis of studies investigating reactivity to infant affective cues (faces, cries).
• Inclusion of structural and resting-state brain imaging data related to maternal substance use.

Main Results:

• Five studies show altered reactivity (hypo- and hyper-reactivity) to infant affective cues in mothers with substance use.
• Three studies report structural and resting-state brain differences associated with maternal substance use.
• Evidence suggests maternal substance use is linked to differential brain responses to infant cues.

Conclusions:

• Human neuroimaging research confirms associations between maternal substance use and altered reactivity to infant affective cues.
• Further multi-level, multi-modal, longitudinal, and dimensional research is essential.
• Advancing this field requires a comprehensive approach to understanding the maternal brain in addiction.
